Changing timing belt and timing belt bearing is a very long and lenghty procedure. While changing belt it is advisable to change the bearing and vice versa, to not to open engine and spend money and time after 6 months for another part.
Mechanic is right and let him change both, belt isnt very expensive but changing labor must be.
No, its not normal. Had same sonata 2 years back and it was fine. Check brake pad and drum may be some need change, also check brake fluid if its topped up properly or not.
Last thing to doubt is ABS, Advance Braking System. It suppose to activate in VERY VERY HARD BRAKING and it jerks the tyre to protect not to skid the car. But in normal braking it shudnt interfere like this.

Insert in driver door and lock the car with key and then press lock button on remote. Do same when u unlock car and it will set the key and battery.
As per hyundai you shud use PSF-3 (Power Steering Fluid), go to hyundai and buy a small bottle and top up by yourself. You will not do any harm if you top up, whereas you will def do harm if you dont get top up soon.
In engine bay look for some small bottle on whose cap says Steering fluid or PSF or Steering wheel icon is made.
Dont forget to move steering left and right and then again top up before you close the cap.
Remove hazard switch and check wiring is fine or not. If wiring wasnt loose and have same behaviour after refixing hazard switch, change new hazard switch as indicator relay is inside hazard switch.
